A few weeks ago, we came across an interesting infographic about email marketing, published by 99firms. We liked it so much that we want to make it available for you here!

Nowadays, there are more marketing channels than ever before in human history. Email is arguably the most powerful strategy for both B2B and B2C advertisers, even if it’s no more 1996, when we were always super excited to receive a new email ;-)!

Email marketing is a cost-effective solution, enabling you to reach potential customers at the place they come visit every day – their inbox.

Just sending email from time to time is not enough. Your potential customers receive dozens of emails every day. But only open a small part of them, and worse, engage with even fewer.

You need a strategy. And you need to learn the most efficient hacks, too. Enjoy the infographic!
